  • Patent number: 11855337
    Abstract: A capacitively loaded loop antenna for an implantable medical device is disclosed comprising a feed extending from a conductive surface of an implantable housing, a radiating element having a cross section larger than the feed, and a return coupling the radiating element to a conductive surface of the implantable housing. The radiating element can have a height above the top surface of the implantable housing, creating a capacitance between the radiating element and the conductive surface of the implantable housing configured to counteract the inductance of the capacitively loaded loop antenna.

  • Patent number: 11247060
    Abstract: Implantable medical devices including interconnections having strain-relief structure. The interconnections can take the form of flexible circuits. Strain relief gaps and shapes are integrated in the interconnections to relieve forces in each of three dimensions. In some examples, the region of an interconnection which couples with a component of the implantable medical device is separated by a strain relief gap from a connection to a second component and/or a location where the flex bends around a corner.

  • Patent number: 9379507
    Abstract: The present subject matter provides feedthrough or interconnect systems for components of an implantable medical device and methods for their manufacture. A feedthrough system includes a wire or nailhead having a protruded tip. The wire or nailhead extends from an aperture in an encasement of a first component and is connected to a terminal conductor adapted to electrically connect to circuitry within the encasement. A ribbon wire has a distal end adapted to electrically connect to a second component and a proximal end having a pattern adapted to fit to the protruded tip of the wire or nailhead to provide for subsequent attachment of the ribbon wire to the nailhead.

  • Patent number: 8954150
    Abstract: The present subject matter provides apparatus and methods for manufacturing an encasement for a component of an implantable medical device having a main circuit board. The method includes forming an encasement aperture on a lateral side of the encasement. The lateral side of the encasement is adapted to be placed substantially parallel to a surface of the main circuit board. A feedthrough assembly is connected through the encasement aperture. The feedthrough assembly includes at least one terminal conductor at least partially passing through the encasement aperture.

  • Publication number: 20140332652
    Abstract: A gas strut support can include a first end and a second end opposite the first end. The first end of the gas strut support can be configured to attach to a first portion of a gas strut, and the second end of the gas strut support can be configured to attach to a second portion of the gas strut. The gas strut support can prevent a piston rod of the gas strut from retracting into a cylinder of the gas strut when a compressive force is applied between the piston rod and the cylinder of the gas strut. The gas strut support has a wide array of applications including, but not limited to, automotive, domestic, and industrial applications.

  • Patent number: 7955288
    Abstract: A swab comprising gelatine or collagen has been found to have a remarkably high recovery of microorganisms. Furthermore, the samples, such as microorganisms, spores, nucleotides and other biologically or biochemically relevant compounds can be fully recovered from the collagen-or gelatine-comprising swab. The invention thus provides a method and swab which has a high recovery of a target from a sample and furthermore a second high recovery when transferring from the swab to a medium for analysis.
